Simultaneously writing to sqlite3 database is not possible. Process exclusively
locks the database for this. Another process will fail to perform any request
when database is locked. Alternatively it can wait. Handling this situation
properly requires complexity that is not really needed. Users are not expected
to run multiple openmw processes simultaneously using the same navmeshdb.
Before this change running multiple openmw processes using the same navmeshdb
can lead to a crash when first transaction fails to start because there is
exception thrown and not catched.
Remove use of explicit transactions from DbWorker. Handling all possible
transaction states due to different errors brings unnecessary complexity.
Initially they were introduced to increase time between flushes to disk. This
makes sense for navmeshtool because of massive number of writes but for the
engine this is not an issue.
Engine controls lifetime of managers therefore it should own them. Environment
is only access provider.
This allows to avoid redundant virtual calls and also some functions from
managers base classes can be removed if they are used only by Engine.

1 with the data directories
2 with the BSA archives
3 with the content selector
When user select a directory to be added, first we walk the directory
hierarchy to make a list of all potential data= entries. If we find
none, the selected directory is added.
If more than one data directory is found, user is presented with a
directory list to check which one(s) are to be added.
Directories containing one or more content file are marked with an icon.
data= and fallback-archive= lines are handled like content= lines:
- they are part of the profile in launcher.cfg, prefixed by the profile
name
- they are updated in openmw.cfg when profile is selected / created
Directories can be moved in the list by drag and drop or by buttons.
Insertion is possible anywhere in the list.
Global data path and data local are shown but are greyed out, as they
are always included.
No attempt is made to ensure that the user choice are valid
(dependencies, overwrite of content).
After a profile is loaded, any added content is highlighted in green.
high_resolution_clock may not give real time. MSVC implements it as
steady_clock that is basically CPU time which is usually desynchronized with
real time.
